2.4 Choice of Lens Mount
The EOS C300 Mark II is delivered with a standard Canon EF mount. This mount can be
removed (at a Canon service center) and be replaced by a choice of the standard PL mount or
an alternative EF mount that has a positive locking system.

2.5 Innovative Cooling System
The broad experiences gained with the first generation C300 emphasized that these
camcorders are often subject to severe environmental conditions. The C300 was unusual in its
quite low overall power consumption – totaling less than 5 watts during recording – and its
cooling system proved adequate. The C300 Mark II consumes more than twice the power of
the C300 (because of more powerful video processing and greatly extended on-board recording
capabilities), and accordingly, a more sophisticated cooling system has been incorporated. Die-
cast parts increase the diffusion of heat and the forced-air cooling system has been enhanced
with two fans that ensure the discharge of the hot air outside of the camcorder body – Figure 8.

cooling fans drive this out of the body
